Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 89 words
A three dimensional model landscape apparatus, the apparatus being representative of an actual landscape including surface area and capable of supporting a plurality of structures, the apparatus comprising: a baseboard assembly having a plurality of apertures; a plurality of terrain cell units adapted for mounting within said apertures, each of said terrain cell units being representative of a section of surface area, said terrain cell units selectively having depressions formed therein; fastening means for securing structures to said baseboard assembly, said fastening means adapted for mounting within the apertures.
Claim 2
Dependent Claim 89 words
A three dimensional model landscape apparatus, the apparatus being representative of an actual landscape including surface area and capable of supporting a plurality of structures, the apparatus comprising: a baseboard assembly having a plurality of apertures; a plurality of terrain cell units adapted for mounting within said apertures, each of said terrain cell units being representative of a section of surface area, said terrain cell units selectively having depressions formed therein; fastening means for securing structures to said baseboard assembly, said fastening means adapted for mounting within the apertures.
Claim 3
Dependent Claim 29 words
The apparatus as defined in claim 1 wherein said terrain cell units are adapted for mounting within said apertures by providing a protruding portion extending from the underside thereof.
Claim 4
Dependent Claim 29 words
The apparatus as defined in claim 2 wherein the dimensions of said protruding portion correspond exactly with the dimensions of the apertures so as to provide frictional engagement therewith.
Claim 5
Dependent Claim 12 words
The apparatus as defined in claim 1 wherein said apertures are square.
Claim 6
Dependent Claim 30 words
The apparatus as defined in claim 1 wherein 100 of said apertures are formed in each of said baseboard assemblies, the apertures being arranged in a 10 by 10 matrix.
Claim 7
Dependent Claim 64 words
The apparatus as defined in claim 1 wherein said fastening means has a top surface and includes a central cylindrical bore, a pin adapted for rotatable mounting within said bore and having a part thereof projecting above the top surface of said fastening menas, said pin being appropriately sized for locking engagement with an irregularly shaped aperture provided in the underside of the structure.
Claim 8
Dependent Claim 17 words
The apparatus as defined in claim 6 wherein said pin allows for rotation to 16 discrete positions.
Claim 9
Independent Claim 23 words
The apparatus as defined in claims 1, 2, 3, 4, 5, 6, or 7 including means for recording the position of said structures.
Claim 10
Independent Claim 26 words
The apparatus as defined in claims 1, 6, or 7 where said structures can be disassembled to allow for inspection of the interior of the structures.
Claim 11
Dependent Claim 29 words
The apparatus of claim 9 where said structures can include buildings, the buildings having several floors, each floor capable of being arranged in accordance with a given floor plan.
Claim 12
Dependent Claim 14 words
The apparatus of claim 10 including means for recording the arrangement of each floor.
Claim 13
Independent Claim 23 words
The apparatus of claims 1, 6, or 7 where said structures can be representative of naturally occuring terrain features or man made features.
